Pour opening for liquid containers

Abstract

An improved easy-opening end closure wherein the end panel is formed with a number of intersecting, straight score lines which define a number of interconnected non-detachable openable segments adapted to be pushed inwardly to open the closure. An opening member is provided, adapted to effect opening of the closure pursuant to a panelwardly directed application of digital pressure on the nose portion thereof, and having a number of camming surfaces for fracturing the score lines and for urging the segments inwardly.

I claim: 
     
       1. An improved easy-opening end closure for a can or similar container, comprising an end panel and an opening member, said end panel having a plurality of substantially straight, interconnected score lines formed therein, the distal ends of said score lines defining the apices of a substantially rectilinear openable member comprising a plurality of substantially rectilinear segments each having at least two sides thereof defined by said score lines and a side comprising an integral hinge nonremovably attaching said segments to the remaining portion of said end panel, means non-removably attaching said opening member proximate one end thereof to said end panel, said opening member being adapted to effect opening of said openable member pursuant to a panelwardly directed application of digital pressure on the opening member distal end, said opening member distal end including force concentration means for focusing an initial opening force proximate at least one of said score lines and a plurality of camming surfaces adapted to separate said segments and urge the same into the container subsequent to initial fracture of said one of said score lines, said opening member being attached to one of said segments. 
     
     
       2. The invention according to claim 1, wherein said opening member is foldable about a portion thereof to bring said force concentration means to an opening position proximately overlying at least one of said score lines. 
     
     
       3. The invention according to claim 1, and offset portions formed in said segments and adapted for cooperation with said camming surfaces. 
     
     
       4. The invention according to claim 1, wherein said segments are substantially triangular.
